Volunteer job,gain experience instead

I come from a small country, Moldova.In the UK I have been for four years, working in amusement industry as Service Engineer.
I studied The Chisinau Polytechnic Coleege,Specialty-Automation and Computer Science.
After that I followed Technical University of Moldova,Specialty-Automatic Control an Informatics.
In 2014 I got a job for the Center for Combating Cyber Crime as digital forensic analyst.We were trained by NCA and FBI specialists(I also have certificates).

Now read, learn, develop myself to get a job in this industry here,in UK.

I want to offer my time and knowledge,in return I would like to get work experience.

Thank you for your advice.
